From recent reviews:
The book contains detailed and fascinating investigations of the methods of the ancient historians of Greece and Rome for the light they are claimed to shed upon those of the New Testament writers. Whenever an ancient source is quoted, not only is an English translation given in the text, but the original language of the example is also reproduced in a footnote. Fascinating also are the discussions of relevant passages in the New Testament such as Lk 1:1-4; Jn 19:35; 21:24; and 1 Jn 1:1-4.
In this well-produced volume the author has reviewed a vast amount of ancient and modern literature on a subject of vital importance for assessing the historicity of the gospel tradition.
